If you’re near the LAX airport today there will be a ceremony where the “public, airport employees and passengers are invited to form a silent human Circle of Unity around the Theme Building ” at noon.
From abc news:
A wreath laying ceremony by the Los Angeles Airport Police Honor Guard will be held at 12:30 p.m. at the LAX Flag Court at Century and Sepulveda boulevards.
The Honor Guard will lay a wreath at the base of the U.S. flag, where a bronze plaque was dedicated on the first anniversary of 9/11. The plaque bears the names of all those who died on the four California-bound flights.
The Transportation Security Administration LAX Choir will sing at the wreath laying ceremony.
